How are ferns and trees alike and different and what would survive longer without rain fern or tree

Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?
